Enhance Varicose Vein Detection with Deep Neural Network

Varicose veins, a prevalent vascular disorder, manifest as enlarged, twisted veins, mostly in the legs, and are painful and seriously complicated by ulcers and deep vein thrombosis if left untreated. Conventional diagnostics, including physical exams, Doppler ultrasound, and venography, are invasive, time-consuming, and highly dependent on expert interpretation, tending to delay early diagnosis. This research leverages deep learning to improve varicose vein diagnosis with the goal of improving accuracy and reducing dependence on manual processes for timely interventions. We trained two deep-learning models on a robust dataset of pre-processed images of varicose veins. The first, a specialized Convolutional Neural Network (CNN), employs several layers to capture spatial hierarchies to achieve a 93% accuracy rate in classifying the stages of varicose veins on the test set. The second, a transfer learning model from ResNet50 with special layers, achieved only 63% accuracy, which suggests relatively lower suitability for this task. Normalization and resizing of data ensured equal processing for all models. Performance was exhaustively evaluated with precision, recall, and F1-score measures, showing the superiority of the custom CNN in specific medical imaging. These findings underscore the effectiveness of customized CNNs compared to general-purpose pretrained models in specialized diagnostic use, holding promise to transform varicose vein care delivery. Implementation of such AI-powered tools in clinical practice has the potential to streamline diagnosis and enhance patient outcomes.
